Standard materials are essential “scales” and “weights” for chemical and biological testing activities. The reporter learned yesterday that the General Administration of Market Regulation recently approved the world's first national-level standard substance for collagen purity developed by the China Institute of Testing Technology, marking an important technological breakthrough in the field of accurate measurement of macromolecular proteins in China. The organic purity of the main component of the collagen purity standard substance approved this time reached 99.58%. It has mastered key core technologies in raw material preparation and accurate valuation, and has completely independent intellectual property rights. It is the first in the world.
